THICKNESS

 

Description: This function allows the user to calculate and apply a nodal thickness value for each part of the model.

 

The calculation of the thickness is made via a “one-step” metalforming analysis. As the part is selected, a background process calculates the nodal thickness values based on material properties, the shape of the component, and the initial component thickness.

 

Note: This process is available only on HP-UX operating systems and requires an additional license key.

-AUTO NORMAL

 

Description: The calculation method used to create nodal thicknesses requires that all elements be consistent with respect to normals. This requires element connectivities to be defined in a consistent manner. This function allows users to check the connectivity definitions for the components and reverse any elements that are inconsistent.

 

Usage:

1.     DSI prompts:

>  SELECT PART FOR AUTO NORMAL 

-All Active Parts

-Cursor Pick Part

 

2.     After the user selects the desired parts, DSI prompts:

>  IS NORMAL DIRECTION ACCEPTABLE? (Y/N)

 

-CALCULATE

 

Description: This function executes a background process that uses component geometry, material, and thickness to calculate a nodal thickness and residual strain value.

 

-READ DYNAIN

 

Description: This function allows users to read a DYNAIN file from a previously executed LS-DYNA metalforming analysis.

 

Usage:

          1.  DSI prompts:

>  INPUT DYNAIN FILE NAME

 

 

-READ CONTACT PRESSURE

 

Description: This function allows users to read a pressure file from a previously executed LS-DYNA metalforming analysis.

 

Usage:

          1.  DSI prompts:

-MAP PRESSURE

 

Description: This function allows users to map pressure from a part to another part
